Whiten teeth and eyes in Photoshop

There are quite a few tutorials available on this topic via Google search. Most of them involved destructive editing, i.e., to undo editing you had to use Edit>Undo or History.
This method uses layer mask so if you want to go back a couple of steps, you just have to change foreground colour by hitting X and painting over the edited area.

Comments and suggestions are welcome.
